A madman with a machete chased a man out of his Bedford-Stuyvesant home yesterday and sliced him across the chest before fleeing, sources said.

The victim, identified only as Kerry, was chased from his basement apartment at 1327 Prospect Place, neighbors said.

“This guy walked up and started shouting, ‘Where’s Kerry?’ ” said a neighbor who requested anonymity. “. . . Ten minutes later . . . Kerry comes running out and the guy chases after him and stabs him.”

Kerry’s condition was not immediately known last night at an area hospital.
